So before it was asked if you had to be ambassador to use the certificate and the answer focused on ID so I think they made the assumption that it would be used by different person.
I need to re-ask with more detail.
I am currently ambassador with a BOGO certificate that expires after my ambassador expires.
Has anyone had success booking BOGO while ambassador and then using that BOGO certificate for that booking that happens to when you are no longer ambassador (ambassador expires prior to your booking)?
